摘要:
虚拟知识图谱(VKG)构成了集成和访问遗留数据源的最有前途的范式之一。集成过程中的一个关键瓶颈涉及将数据源链接到领域本体的映射的定义、验证和维护。为了支持映射在整个生命周期中的管理,我们提出了一个全面的复杂映射模式目录,这些模式在将数据库链接到本体时出现。为此,我们建立在数据管理、数据分析和概念建模中研究的成熟方法和模式之上。通过分析具体的VKG基准和实际用例,并考虑数据源与本体之间固有的阻抗失配,对这些方法和模式进行了扩展和细化。我们在所考虑的VKG场景上验证了我们的目录,表明它覆盖了其中存在的绝大多数模式。
英文摘要:
Virtual Knowledge Graphs (VKG) constitute one of the most promising paradigms for integrating and accessing legacy data sources. A critical bottleneck in the integration process involves the definition, validation, and maintenance of mappings that link data sources to a domain ontology. To support the management of mappings throughout their entire lifecycle, we propose a comprehensive catalog of sophisticated mapping patterns that emerge when linking databases to ontologies. To do so, we build on well-established methodologies and patterns studied in data management, data analysis, and conceptual modeling. These are extended and refined through the analysis of concrete VKG benchmarks and real-world use cases, and considering the inherent impedance mismatch between data sources and ontologies. We validate our catalog on the considered VKG scenarios, showing that it covers the vast majority of patterns present therein.
